MessageBeep
The MessageBeep function plays a waveform sound. The waveform sound for each sound type is
identified by an entry in the [sounds] section of the registry.
BOOL MessageBeep(
UINT uType
| // sound type
| );
|
|
Parameters
uType
Specifies the sound type, as identified by an entry in the [sounds] section of
the registry. This parameter can be one of the following values:
Value
| Sound
| 0xFFFFFFFF
| Standard beep using the computer speaker
| MB_ICONASTERISK
| SystemAsterisk
| MB_ICONEXCLAMATION
| SystemExclamation
| MB_ICONHAND
| SystemHand
| MB_ICONQUESTION
| SystemQuestion
| MB_OK
| SystemDefault
|
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
After queuing the sound, the MessageBeep function returns control to the calling function and plays the sound
asynchronously.
If it cannot play the specified alert sound, MessageBeep attempts to play the system default sound. If it cannot play the system
default sound, the function produces a standard beep sound through the computer
speaker.
The user can disable the warning beep by using the Control Panel Sound
application.
